That's OK for Chinese. We are used to find a key that is not related
to the translation. And you might know that we have to hit various
keys to compose a character. That is not efficient to hit 'qss ' (the
first character for 'reject' using Chang Jei method) instead of 'r'.

No matter wheter it's an 'R' in German or other language for 'Reject',
I'll just stick with 'R'. :)
